Essential Questions EQ1 -- Is it ever advantageous to create a design or solve a problem individually as opposed to using a team approach? Explain. EQ2 – What strategy would you use to form a design team in order to obtain the best solution possible? EQ3 – What does it mean to be “ethical” in your work? Do engineers need to be taught to be “ethical”? EQ 4 – It has been said that, “Having a vision without action is a daydream; Taking action without a vision is a nightmare!” How does this apply to engineering design? Unit 10: Design Challenges In this unit students will work in small collaborative teams, implement the design process, and use skill and knowledge gained during the course to solve a culminating design challenge and document and communicate their proposed solution. Understandings Students will understand that … U1 (Unit 1) – An engineering design process involves a characteristic set of practices and steps used to develop innovative solutions to problems. Knowledge and Skills KNOWLEDGE: Students will … K1 – Identify the steps in an engineering design process and describe the activities involved in each step of the process. SKILLS: Students will … S1 – Develop and document an effective solution to a problem that meets specific design requirements. U1 S2 – Document and describe the design process used in the solution of a problem and reflect on all steps of the design process. 14 Essential Questions EQ1 – Engineering has been referred to as the “stealth” profession. Do you think this is an appropriate label? Explain. EQ2 – If you had to describe one strategy that would most help an engineer be a good and effective designer, what would it be? CULMINATING PRODUCT(S) Students will develop a website to act as an electronic portfolio of their coursework. Students will develop engineering design project including planning, design, creation, and evaluation steps.
